Question
The child has had a persistent low fever of 39.0°C or higher for six days, accompanied by cough, loss of appetite, and low fever in the afternoon and at night, reaching 40.5°C. During the fever, the child’s hands and feet are cold, and there is a dry throat and itching. The onset was at 10 PM on November 16th, and the laboratory results show a C-reactive protein level of 25. The child has previously undergone four days of intravenous treatment (amoxicillin, cephalosporin anti-inflammatory drugs), but the effect was not significant.
Answer
Based on your description, the child may have tuberculosis or other diseases and should undergo relevant examinations, such as tuberculosis antibody testing, tuberculin skin test, sputum smear examination, etc. If the child has a history of playing in grassy areas, consideration should also be given to scrub typhus, checking for eschar in hidden areas such as armpits and the groin. It does not appear to be influenza A, as there are no symptoms of general malaise, fatigue, cough, or runny nose. It is recommended to seek medical attention promptly and consult with a professional for advice and treatment.
